End of Firewalls-Digest V8 #1076
********************************

To unsubscribe from Firewalls-Digest, send the following command
in the body of a message to "[EMAIL PROTECTED]":

unsubscribe firewalls-digest

If you want to subscribe or unsubscribe an address other than the
account the mail is coming from, such as a local redistribution list,
then append that address to the command; for example, to subscribe
"local-firewalls":

subscribe firewalls-digest [EMAIL PROTECTED]

A non-digest (direct mail) version of this list is also available; to
subscribe to that instead, replace all instances of "firewalls-digest"
in the commands above with "firewalls".

Compressed back issues are available for anonymous FTP from
Lists.GNAC.NET, in pub/firewalls/digest/vNN.nMMM.Z (where "NN"
is the volume number, and "MMM" is the issue number).
